' To all whom it may concern:

Be it known'tha-t ERNIE ADAMSON, a citizen of the United States of America, residing atAtlanta, in the county of Fulton and State of Georgia, has inventedcertain new and useful Improvements in Acetylene-Gas Generators, of which the following is a specification. y

The present invention relates to improvements in acetylene gas generators of the ebb and flow, or kissing type whereinthe generators contain ,carbid to which the water is admitted by an ebb and flow movement produced by pressure of gas in the generator.

The primary object of the invention is the provision for "an efficient, portable, self contained, generator for acetylene gas, that is compactly arranged and in which the different parts are easily accessible, rendering the device particularly simple in construction and facile in its operation. The invention consists in certain novel combinations and arrangements of parts as will be hereinafter described and claimed.

, In the accompanying drawings there is one complete example, and a modification thereof, in which the physical embodiment of the invention is illustrated, constructed and. arranged according to the best mode so far devised for thepractical application of the principles of the invention.-

; Eigu-ie 1 is a vertical sectional view of the preferred form of the invention; 1 Fig. 2 is atransverse sectional view at line 2-2 of Fig, 1. y

Fig.1 5 is atransverse sectional view at l Fig. 6 is a similar view at line 6-6 of nthe preferred form of the invention as illustrated in Figs l, 2, and 3, a tank or outer-cylindrical casing 1 15 provided, pref- ,erably of metal and cylindrical in shape, be-

a t ofthetankthe water chamber or reservoir W is indicated, andin the lower part of a the tank is located thegas bell 5 haviugan open bottom and closedtop (3, the gas chainberbelng designated G. i

The bell is retained in the I mink through the instrumentality of'an' inverted U-shaped yoke 7 the legs of which are at tached to the outside of, the cylindrical bell, and the yoke projects upwardly "a suitable distance to engage under the diametrically arranged angle brackets 8' attached to the inner wall of the cylindrical tank, the yoke being ofinetal possessing suflicientresiliency to permit forcing the yoke, under the brackets to holdthe bell in position.

\Vithin the bell is inclosed a third cylindrical member or receptacle 9, open at both I encls,fand providedwith three for-aminous partitions, as 10, 11, and 12, the first designed to support the oarbidC in the upper partofthe receptacle, the second or intermediate partition designed to catch the car bid as it falls from the bottom of the carbid supply C, and permit the broken carbid, while onthis intermediate partition,.to be fully and completely decomposedandidisintegrated before passing through this partition and falling, inthe form of ashes upon the plate 13 011 the partition 12. at thebottom of the receptacle.

A- pair of lateral openmgs 14 are provided in the walls of the receptacle, just below the top partition or carbid-support, and about in the same plane with the intermediate partition 11, so that water may; pass a through these two openings or ports from the lower part of the bell to the interior of the receptacle, and contact with thetcarbidthrough the foraminous partition orsupport 10. i

The carbid receptacle is centered and sup-,,

ported within the hell by means of a number of braces 15,;that: are preferably made of resilient metal in order/to frictionally en- 1 gage theinner walls of the bell and hold the a receptacle, stable, and one of these braces,

also supports an oil: vessel or chamber 16, located at the exterior of the receptacle within the bell and ,designedito contain oil that will flow from its open top and form a layer on the top of the water as it rises in the bell and contacts with the carbid so that the carbid comes in contact with water a under the oil,,thuspreventing generation of steam and premature breaking down of the carbid. n

, project diametrically from theexterior of the receptacle, and the bayofiet 'notehes' 17"! in the lower edge 01": the bell, the bell 1s held ,elevated a sufficient: distance above the 'bottom of the tank to permit circulation of the Water.
